Routing power through intermediate unit
You can route the main power supply through an intermediate unit (type PA1 or PA2) before
connecting the power to a PA0 type unit. This chapter describes how to make the connections
for this configuration. You must change the connectors, because the 5-pin power out
connector from the PA1 or PA2 unit does not match to the 3-pin power input of the PA0 power
supply. The illustration below shows:
